SAFETY DEVIQE FOR GAS STOVES.

Application filed July 28,

This invention relates to protective de vices for gas stoves, and moreparticularly to a shield adapted to be mounted on a gas stoveeffectively preventing accidental operation of the controlling valves;and its primary object is to provide a shield of a novel and improveddesign adapted to be mounted upon the supply pipe of an ordinary gasrange, effectively preventing tampering with or accidental operation ofthe gas cocks when the shield is located in position.

Another object of the invention is to pro vide a device of the characterspecified, which is extremely simple in construction, being made in asingle piece and which is readily attachable onto or detachable from agas stove or range without the necessity of using screws or bolts.

Other objects and advantages of the present invention will more fullyappear as the description proceeds and will be set forth and claimed inthe appended claims.

The cocks controlling the flow of gas in an ordinary gas stove or rangeare usually so constructed that they may easily be thrown open or closedby accidental contact with their handles, when a person passes close tothe stove.

Accidents due to gas cocks being unwittingly operated by children or byinexperienced persons are also of a frequent occurrence, and thereforeit is desirable that some protection be afforded to the feed system of aheating appliance in order to protect the valves Or cocks againstoccurrences of this nature, with their attendant dangers.

With these objects in view I have devised a shield of a simple andinexpensive construction, which effectively prevents operation of thecooks by completely enclosing them when set in position; the operationof said cocks becoming only possible when the shield is swung outwardlyto a sufficient extent permitting access to the gas control system.

In the accompanying drawings, I illustrate the construction and generalappearance of my device, and in the same- Fig. 1 is a fragmentary planView of an ordinary gas cooking range showing my device applied inposition;

view in elevation through line 33 of Fig. 1, showing a gas cock open andthe protective device set in position;

Fig. f is similar view showing the protective device moved to its openposition to permit operation of the gas cocks;

5 is a front view in elevation of a device embodying my invention, madecollapsible in order to it stoves of different sizes; and

Fig. 6 is a cross sectional view in elevation of the same.

In said drawings, Figs. 1 to at, 10 designates an ordinary gas range,provided with a front supply pipe 11 running along the front thereof.Said supply pipe is provided with cocks such as 12, controlling the flowof gas to the range, said cocks being locatea in the space interveningbetween the supply pipe and the front of the range. The supply pipe ismounted on the range by means of brackets 13, 14, and is ordinarilv heldat a distance from the front of the stove and at a level somewhat belowthe level of the stove plate, as shown.

My improved device consists essentially of a shield lei, comprising amain or body portion 15 running practically for the oritire length ofthe supply pipe and enclosing the space above the cooks between thesupply pipe and the front of the range, and a lower pivotal supportingportion 16 adapted to be inserted over the supply pipe. Said bodyportion is curved at the rear as shown at 17 in order to clear the outerend of the cock handles when open as shown at 12 in Fig. 3, and its rearsurface preferably rises to a point 18 a few inches above the surface ofthe top of the range and is then bent downwardly at 19 and then inwardlyforming a horizontal flange 20 abutting against the top of the rangewhen the device is set in position as shown at Fig. 3.

Said flange 20, is preferably provided with an opening 21 through whicha key or other locking means 22 attached to the top of the range mayproject locking the device in position.

The lower or pivotal supporting portion 16, has a semi-circular inneroutline to fit the diameter of the supply pipe, extending from a bend23, connecting its inner edge to the lower edge of main body portion 15,around the supply pipe and then to its lower or outer edge 24, extendinga certain length from said supply pipe towards the front of the stove.

The device is completed by two end walls 25, 26, closing the cockcompartment completely and extending downwardly, leaving a clearancespace such as 27 ahead of edge 24 of the pivotal supporting portion,providing sufficient room for the passage of supply pipe 11, thuspermitting the easy insertion of the device over said supply pipe andits easy removal therefrom.

However, if desired, pivotal supporting portion 16 may be omitted, theend walls being made to extend to the rear of the supply pipe so that 27becomes a slotted passage as shown and the end walls themselvesconstitute the pivotal support for the device.

The lower end of each side wall extension is formed with a forwardlyextending hook portion 28, which engages the lower front edge 29 of thetop of the stove or range when the device is tilted outwardly about thepivotal support provided by supply pipe 11 to the position shown in Fig.4.

The rear edge 30 of the front end wall extensions forms substantially acontinuation of the inner surface of pivotal supporting portion 16 whensaid pivotally Supported portion is used, and therefore it will assistsaid portion 16 in supporting the device when said device is tiltedoutwardly; so that the combined supporting effect of the inner surfaceof pivotal supporting section 16 and rear edges 30 of the end wallextensions together with the stop provided by hook portions 28 abuttingagainst edge 29 of the top plate, cooperate in preventing the devicefrom coming off when tilted to the position of Fig. 4.

The only position in which the device can he removed is that shown inFig. 3, where the removal can be effected by shifting the deviceupwardly in a direction inclined about 15 to the rear and then bytilting the device outwardly as clearance space 27 reaches supply pipe11.

In Figs. 5 and 6, I show a modified construction where the lower orpivotal supporting portion is omitted, the support of the device beingprovided entirely by the end walls. The device is further modified bybeing made in two pieces, that is, a main body or hood proper and an endmember or sup port having a portion telescoping within said hoodportion, thus forming a collapsible structure, adapted to be used inconnection with stoves of different sizes.

In said drawings, 31 designates the main or hood portion made integralwith end wall 32, and 33 designates the end member telescoping withinhood 31, said end members being provided each with an end wall 34,similar to end wall 32. Each end wall is therefore provided with aslotted passage 35 which can be inserted over the gas supply pipe 86, asshown in Fig. 6, in all other respects the device being similar to theone previously described.

From the foregoing it will be observed that I provide a structure ofexcessively simple design and construction, which can be quicklyinserted in position and removed therefrom without requiring theaddition of any parts to the stove itself, and without the use of screwsor bolts.

It is obvious that with minor modifications, the device may be madeadaptable for use in connection with different types of gas ranges. Thedevice may be made out 0 sheet metal or cast iron and effectivelyprotects the handles of the cocks against tampering or accidentalopening or closing.

It will. be observed that by extending the body of the shield to aheight well above the top of the range, thekey or other locking meansused will remain concealed from view and out of reach of the averagesmall child.

The drawings are intended for-illustrative purposes only and not in alimiting sense, because the invention may vary in itsv details from theembodiment shown. Therefore, I reserve myself the right to carry myinven tion into practice in any way or manner which may enter fairlyinto the scope of the appended claims.
